Rafa Martí is Professor in the Statistics and Operations Research department at the University of Valencia, Campus de Burjassot, Valencia, Spain. His teaching and research are devoted to Statistics, Mathematical Programming, and Heuristic Optimization. He is co-author of seven books, being the last one Discrete Diversity and Dispersion Maximization (Springer 2023), and has secured an american patent. Prof. Martí is currently Area Editor in the Journal of Heuristics and Associate Editor of the European Journal of Oper. Res., TOP-Transactions in Ops. Research, the Math. Prog. Computation, and the Int. Journal of Metaheuristics. He coordinates the Spanish Network in Metaheuristics, currently funded as a SEIO working group and by the Spanish Goverment.

Prof. Martí has published almost 200 papers, and around 125 are in JCR-indexed journals (h-index=58 and i10-index=147 according to Google scholar). He has also contributed with around 100 presentations in conferences and universities, from which about half of them were invited. Martí is Senior Research Associate of OGA (Consulting), and has been invited professor at the University of Colorado (USA), Molde (Norway), Wien (Austria), Bretagne-Sud (France), UCD (Dublin), and Panamá. The Web of Knowledge, compiles 136 of his papers and computes an h-index=34. (Download curriculum vitae).

OGA

Data driven solutions

OGA is a company specialized in Artificial Intelligence and Operations Research that bases its value contribution on the development of digital twins of critical business processes in sectors such as industrial, logistics or defense. OGA provides services to top companies such as Indra, Coca-Cola, Iberdrola, or Abengoa. OGA creates data-driven business solutions in critical processes such as production or logistics of all types of organizations.

The collaboration between Prof. Martí and OGA started in 2022 when he joined the Catedra board of technological experts to support their research. Since then, the collaboration has been extended with a contract (Feb. 2024) between the University of Valencia and OGA to directly participate in optimization projects.

SCOOP - OPTSICOM

Research project

Rafa Martí and Anna Martínez-Gavara coordinate the research project entitled Supply Chain Optimization (SCOOP) This is a joint project with Rey Juan Carlos University (URJC) and includes 20 researchers. In this project we develop algorithms, based on metaheuristic methods, which integrated in a software, solve hard optimization problems. It is funded by the Spanish Goverment with the code PID2021-125709OB (2022-2024).

The collaboration between our group and the URJC team (GRAFO) started in 2006 when Profs. Martí and Duarte published a paper in the European Journal of Operational Research. Since then, both teams have published together almost 50 JCR-indexed papers and 25 book chapters, and their research has been presented in more than 50 international conferences. This collaboration has received remarkable evaluations on previous joint funded projects, such as: TIN2012-35632, TIN2015-65460 or PGC2018-095322.

In the OPTSICOM website, codes, instances and best known solutions for the problems in which we are working are available. You can directly download from here the LOLIB and MDPLIB 2.0.
